Description

Technical Field

[0001] The present invention relates to the technical field of fish fry sorting, and in particular to fish fry sorting equipment and a method. Background Art

[0002] Fish farming refers to an agricultural production method that uses scientific methods and means to artificially breed, cultivate and manage different fish in indoor or outdoor waters to obtain high-yield, high-quality aquatic products. Different fish have different breeding seasons, and the breeding period of each fish in the same season is different. In order to increase the yield of fish farming and reduce the loss of fry, fish need to be sorted regularly during the breeding season. Fish sorting usually refers to the process of screening the species and size of the caught fish. The purposes of fish sorting mainly include the following: 1. According to the size and growth stage of the fish, the stocking density can be reasonably adjusted to reduce the waste of resources and the risk of disease transmission caused by excessive competition; 2. According to market demand and price fluctuations, select fish of appropriate size for sale to achieve higher economic benefits; 3. During transportation, fish can be effectively managed according to their size and activity, reducing losses caused by squeezing, lack of oxygen, etc.; 4. By sorting the caught fish, the product quality in the subsequent processing and sales links can be guaranteed, thereby improving the quality of the entire industrial chain. By sorting fish, the sustainable utilization of fish resources can be achieved, while improving production efficiency and economic benefits.

[0003] There are many existing methods for sorting fry, mainly divided into two methods: manual sorting and automatic sorting. However, both methods have certain disadvantages, mainly including: 1. During the fish breeding season, the output of fry is high, and the manual sorting method consumes a lot of human resources. At the same time, the fry sorting frequency is high, and the fry sorting efficiency is low. In addition, during the breeding process, due to the high density of fish breeding, some fry are swallowed by big fish, resulting in a large loss of fry; 2. During the manual sorting process, the fry need to be driven away and concentrated, so as to facilitate the collection and sorting of the fry. During the operation, multiple personnel need to work together. For large-scale breeding sites, it is difficult to concentrate the fry; 3. The automated sorting method mainly uses a pump to extract the fish from the pool, and uses screens or sorting devices with different apertures to sort fish of different sizes. However, this method causes great damage to the fry. At the same time, the fish are out of the water for a long time during the sorting process, which can easily lead to the death of small fry and cause fry loss.

[0004] Therefore, a fry sorting device and method are proposed, and fish are sorted in two ways. Meanwhile, the fish sorting is always carried out in the water body to solve the above problems. Summary of the invention

[0005] The present invention provides a fry sorting device and method, which solves the problems in the related art that the fry are not sorted in time, resulting in the fry being swallowed by big fish, the fry sorting efficiency is low, and the fry are seriously damaged during the sorting process.

[0006] The technical solution of the present invention is as follows: The fry sorting equipment comprises a floating ring, the top of which is fixedly connected to a sorting box, a sorting component is arranged inside the sorting box, the sorting component comprises a clamping hole opened at the outer end of the sorting box, an outer screen is fixedly connected inside the clamping hole, a through pipe is fixedly connected to the inner bottom of the sorting box, a through hole is opened on the bottom side of the through pipe, a lighting lamp is fixedly connected to the top of the floating ring, a food box is fixedly connected inside the through pipe, a spinning cloth is sleeved on the inner side of the floating ring, the spinning cloth is arranged inside the sorting box, and an inner screen is arranged at the outer end of the spinning cloth.

[0012] Optionally, the side frames are provided with four groups and are arranged equidistantly in a ring shape, and the suction cups are provided on the lower side of the sorting box.

[0013] The method for sorting fry comprises the following steps: S1. Based on sorting small fry, the floating ring is placed in the fish pond, and fish food is added to the food box fixed inside the through tube; S2. The suction pump is connected to the top of the through-tube, and the suction force generated by the suction pump is extracted from the inside of the sorting box for small fry; S3.

Pull the inner screen connected to the support rod, and the spinning cloth sorts the medium-sized fry and the small fry.

[0014] The working principle and beneficial effects of the present invention are: The present invention can be divided into two ways to sort fry with different growth momentums. One is to sort small fry. By means of the phototaxis of the fry and the trapping of food, the small fry are concentrated in a sorting box, and the small fry are pumped out by an external pump and put into another breeding pond, so as to reduce the probability of the small fry being swallowed by big fish and improve the survival rate of the small fry.

[0028] Example 1 Refer to the instruction manual Figures 1 to 6, which is the first embodiment of the present invention, provides a fry sorting device, including a floating ring 1, a sorting box 2 is fixedly connected to the top of the floating ring 1, a sorting component 3 is arranged inside the sorting box 2, the sorting component 3 includes a clamping hole opened at the outer end of the sorting box 2, an outer screen 301 is fixedly connected inside the clamping hole, a through pipe 302 is fixedly connected to the inner bottom of the sorting box 2, a through hole 303 is opened on the bottom side of the through pipe 302, an illuminating lamp 304 is fixedly connected to the top of the floating ring 1, a food box 305 is fixedly connected inside the through pipe 302, a spinning cloth 307 is sleeved on the inner side of the floating ring 1, the spinning cloth 307 is arranged inside the sorting box 2, and an inner screen 3010 is arranged at the outer end of the spinning cloth 307. The purpose of this arrangement is that during the fish breeding season, the floating circle 1 is placed in the fish pond, and fish food is added to the inside of the food box 305. The fish food attracts the fish to gather at the outer end of the sorting box 2. The outer screen 301 is used to separate large and medium-sized fry, and only small fry are allowed to pass. The pump can be connected to the through pipe 302, and the pipe of the pump is connected to another pool. The suction generated by the pump discharges the small fry into the pool. The sorting equipment can be used at night, relying on fish food and lighting 304 to attract fish. The small fry automatically enters the through pipe 302 by attraction. On the one hand, large and medium-sized fry and small fry can be automatically and quickly separated, providing shelter for small fry, preventing small fry from being swallowed by large and medium-sized fish, reducing economic losses, and the same batch of small fry due to genetic differences. The growth rates of small fry are different due to factors such as the size and variety of the fry. In the process of regularly re-sorting the same batch of small fry, the pump is connected to the through pipe 302, and the fry in the pool are poured into the through pipe 302. The spinning cloth 307 and the inner screen 3010 and the outer screen 301 at the outer end of the sorting box 2 sort the fry again, so that the large-volume fry are retained in the sorting box 2, while the small-volume fry enter the fish pond again through the inner screen 3010 and the outer screen 301. The large-volume fry are collected by pulling the inner screen 3010 connected by the support rod 309. This method can sort high-quality fry with good growth, and the damage to the fry in the operation project is small. The screening of the fry can be completed in the water body, which improves the survival rate of the fry, and the screening of the fry is fast and convenient.

[0029] Optionally, the cross section of the through pipe 302 is in the shape of an inverted funnel, the apertures of the outer screen 301 and the inner screen 3010 are the same, a leakage hole is provided at the bottom of the food box 305, a blocking net is fixedly connected inside the leakage hole, and the aperture of the blocking net is smaller than the aperture of the inner screen 3010. The purpose of this arrangement is that the outer screen 301 and the inner screen 3010 of the same size can sort out small fry of the same size, and the blocking net in the leakage hole at the bottom of the food box 305 facilitates the passage of fish food while preventing small fry from entering the food box 305.

[0030] Optionally, four groups of lighting lamps 304 are arranged in a circular shape with equal spacing, and the sorting assembly 3 further includes a sealing cover 306 threadedly connected to the outer end of the food box 305, a clamp ring 308 is clamped at the top of the through pipe 302, and a support rod 309 is movably connected between the clamp ring 308 and the bottom end of the spinning cloth 307, and four support rods 309 are provided. The purpose of this arrangement is that the sealing cover 306 can prevent the fish food from floating, and when sorting medium-sized fry, the spinning cloth 307 is pulled up by lifting the clamp ring 308, so as to sort medium-sized fry from small fry.

[0031] Optionally, a cavity is provided inside the floating ring 1, penetration holes 4 are symmetrically provided at the bottom of the floating ring 1, and an air pressure tube is symmetrically provided at the top of the floating ring 1, and an air pressure plug 5 is threadedly connected to the outer end of the air pressure tube. The purpose of this arrangement is that the floating ring 1 with a cavity can float on the water surface and the sorting box 2 is placed underwater. By adjusting the content of water and air inside the floating ring 1, the height of the sorting box 2 submerged in the water can be adjusted, and it can be adjusted according to the habits of the fry.

[0032] Optionally, a bracket 6 is symmetrically fixedly connected to the top of the floating ring 1, and a solar panel 7 is fixedly connected to the outer end of the bracket 6, and the solar panel 7 is electrically connected to the lighting lamp 304. The purpose of this arrangement is that the solar panel 7 provides power for the lighting lamp 304 by absorbing sunlight during the day.

[0033] Optionally, the outer end of the sorting box 2 is fixedly connected to a side frame 8, and the outer end of the side frame 8 is fixedly connected to a suction cup 9. The purpose of this arrangement is that the side frame 8 and the suction cup 9 are convenient for adsorbing the sorting box 2 on the bottom of a fish pond with a shallow water depth.

[0034] Optionally, the side frames 8 are provided with four groups and are arranged in a circular shape with equal distances, and the suction cups 9 are provided at the lower side of the sorting box 2. The purpose of this arrangement is that the four groups of suction cups 9 are provided to enhance the stability of the sorting box 2 adsorbed on the bottom of the fish pond, and prevent the sorting box 2 from being overturned due to the collision of large fish.

[0035] Example 2 Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: Compared with Example 1, a further method for sorting fry includes the following steps: S1. Based on sorting small fry, the floating ring 1 is placed in the fish pond, the air pressure plug 5 at the outer end of the air pressure tube is opened, and water enters the cavity inside the floating ring 1 from the penetration hole 4 at the bottom of the floating ring 1. As the gas inside the floating ring 1 is discharged, the floating ring 1 drives the sorting box 2 to sink, so that the sorting box 2 sinks into the water pond, and fish food is added to the food box 305 fixed inside the through pipe 302. The fish food attracts the fish to gather at the outer end of the sorting box 2. Small fry enter the inside of the sorting box 2 through the outer screen 301, while large and medium-sized fry cannot pass through the outer screen 301. The lighting 304 can be turned on at night. The fry have a strong phototaxis, which is also conducive to the fish gathering at the outer end of the sorting box 2. Small fry are sorted, and small fry and large and medium-sized fry can be fed separately. While solving the problem that small fry are difficult to grab food, it can also prevent small fry from being swallowed by large and medium-sized fish; S2. Connect the suction pump to the top of the through pipe 302, and extract the small fry from the inside of the sorting box 2 by the suction force generated by the suction pump. The floating ring 1 can float in the pool to attract small fry at various positions in the fish pond. During regular sorting, connect the suction pump to the through pipe 302, and the suction force generated by the suction pump will extract the small fry gathered in the sorting box 2, so as to facilitate the introduction of the small fry into another fish pond for classification and breeding; S3. Based on the sorting of medium-sized fry, the floating ring 1 is placed in the fish pond, the pump is connected to the through pipe 302, the fry in another pool is discharged into the through pipe 302, the water flow flushes the small fry out of the outer screen 301, and the medium-sized fry are retained between the through pipe 302 and the inner screen 3010. The small fry of the same batch drained to the new pool have different growth trends due to differences in genes and species. In the sorting process, the suction force generated by the pump guides the fry in the pool into the through pipe 302, and the inner screen 3010 and the outer screen 301 filter and sort the fry, so that the medium-sized fry are retained in the sorting box 2, and the small fry enter the pool again through the inner screen 3010 and the outer screen 301. This method can sort high-quality fry with good growth and large-volume fry, and can also prevent small fry from being swallowed by medium-sized fry; S4. Pull the inner screen 3010 connected to the support rod 309, and the spinning cloth 307 sorts the medium-sized fry from the small fry. The sorted fry are retained in the sorting box 2. By lifting the clamp ring 308, the inner screen 3010 connected to the support rod 309 is lifted, so that the medium-sized fry are sorted out, which is convenient for placing the medium-sized fry in another pool for centralized breeding.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
